Pressure Reducing Valve

Q: my dad's friend died, and dad had been keeping some valves of his. now we've been left with about 400 valves and i'm going to sell them.my main question is what are they used for? i need to write a description for ebay but have no idea what they're for! anyone know?also, how much should i sell them for? on the box it says 11 shillings, which i worked out as ?1.32, but how much should i sell them for on ebay? there's prices on ebay that are about 50p to ?1.50 for most of them, but some are about ?7 but have no bids at all. how much should i start the bidding at?also, if you could give me any other information that i should put in the description, i would really appretiate it :)they are mainly 'Mullard' valves (the company name) but some are 'MAZDA'thanks! :D: Valves...or as we call them over here in the states, tubes...have a huge number of uses. These were basically what we had before we had transistors. There are tubes that regulate voltage, tubes that perform logic operations...audio tubes, tv tubes. What each tube does is pretty specific to the type of tube. Each one should be marked with an indentifying mark...such as 12AX7..or what you might see, ECC83 (just examples). Here's the great thing. You don't really need to know what they do. The people that are going to be buying tubes pretty much know what they're looking for. All you're mostly interested in listing is the tube type. You can get fancy, look it up and write down what kind of tube it is. However, you can't really nail down one application. I have tubes that were used in the RF amplifier section for VHF that, surprisingly, make EXCELLENT audio amplifier tubes. They have a wide range of uses...and for selling purposes, you only need to tell people the following: Brand of type type of tube (tube designation). You can include some information if you want...I'd make sure you mention they're untested unless you have a tube tester. But, for the most part, the people that would be interested in buying these things in the first place are already going to know what they're for. They're not something bought by the general public..it's a niche market. What you'll want to do though is look up those same tubes on OKorder to get an idea of what prices are going for. It's entirely possible you have a tube or two that are hard to find in todays market and would bring you MUCH MUCH more than the 11 shillings it retailed for. Case in point...I have a tube that sold brand new in the 60's for around $2....today..that tube can go upwards of 200 because they're not making them anymore. Oh...and make sure you throw the term vacuum tube in there too to get it in broader search results. I haven't heard anyone call them valves....unless they're from the UK.

Q: I have an 98 Mitsubishi Eclipse rs and its a little jerky while driving and i think it might be the PCV valve but I don't know where it is located.. where is it? and would this cause the check engine light to come on?: Your okorder okorder , which covers all Eclipse/Talon models.

Q: Last year an echo revealed severe aortic valve regurgitation with low ef of 37 but ecg was normal. i am 36 yrs old. I have noticed that i often have chest pain when i lie on my left (especially after a heavy drinking or if my bp is high) but the pain subsides when i lie on my right or back. Is it possible that my aortic valve only leaks when i lie on my left side, if so, can I continue living a normal life without needing valve replacement surgery if avoid lieing on my left side. or i'm i fooling myself, is the heart damage progressing silently?: Hello, You don't tell us *why* your doctors think, you developed this problem with your aortic valve in the first place? Has there been any infection of the valve with germs, (bacterial endocarditis)? Did you have Rheumatic Fever as a child? Were you born, with stenosis or regurgitation of your aortic valve? Do you have abnormally early, clogging-up of your artery-linings with cholesterol?

Q: I have a training I will be attending on Valve actuator and subsequently an exam. I need fundamental knowledge of ROV. What are the types of ROV. The Maintenance Of ROV ? and the different Type of ROV actuators: The term remote operated valve is slightly misleading, as it really means remotely controlled valve. Normally the valve actuator is mounted directly on the valve body so that it can open and close the valve. The majority of valves are either rotary ball or sliding gate type. Valve actuators can be operated by electrical methods, pneumatic or hydraulic, or by a combination. The most common types of actuator for industrial use are motorised electrical and pneumatic. Motorised valves will have a reversible motor for opening and closing, whilst pneumatic types will have a double acting cylinder with a 5 port 2 position or 3 position control valve. The control contactors and valves would be located in a control room, possibly controlled by a PLC or similar automation controller. In most cases position feedback will be supplied from the valve by means of limit switches to indicate its position, and in the case of motorised actuators, the running current can be monitored as an indicator of valve condition. If a pneumatic valve is jammed, the actuator will simply stall without damage, but for electrical actuators some form of overload protection is required to prevent excessive current load and overheating. The majority of industrial valves require little maintenance, but regular inspection for security, electrical connections, gland sealing etc should be scheduled at intervals suitable for the working environment.

Q: So I know the main purpose of the EGR valve is to recirculate some exhaust to the cylinders to reduce NOx emissions. However, a mechanic told me that a malfunctioning EGR valve can make the engine run way hotter, and that this can damage the pistons, or other components of the engine, over time. Is that true?: sorry dave. i inadvertenly gave you a bad rating. if the question asker, or someone at answers can, please change my vote to thumbs up. dave nailed it 100%

Q: Leak in Heart Valve ?i was told by my doctor to to do a ultra sound on my heart a few weeks ago, wehn i finished the ultra sound the lady that did the scan asked if i had any type of heart disease in my family, and i responded that i dont, she said that i have a leak in my heart valve, but that was all, i dont have an appointment with my doctor til two weeks from now, i THINK i feel shortness of breath, but i feel like this may all be because im scared ...... main thing is has anyone had this or know anything about this is it dangerous, deadly ? should i be scared ?: It depends on what valve is leaking, how much is leaking, and for how long has it been leaking. Wait for the physician to evaluate the echocardiogram. Technicians are often wrong or limited in their evaluation, as they are not trained in in-depth evaluation of echocardiographic studies like a cardiologist. Make an appointment with your doctor to discuss the results. You said you think you have shortness of breath, make sure you mention that when you make your appointment. Only your doctor will be able to determine if it is related to your heart, or due to anxiety, or from something else.

Q: also are those air flow limiting valves safe for the air pump to reduce the flow of air, I have one because the air bubbles are just way too many without one and it scares the fish away: a check valve is to prevent back siphoning of water into the pump if you have a power outage or unplug the pump by accident. I'd suggest checking it by blowing through it the wrong way; if air does pass through get a new check valve (check new ones to be sure they don't limit airflow too much, and that the close in the wrong direction, many are cheap crap and don't work the day you buy them, so check them before you leave the store with it...note: same with thermometers, compare them with each other so you don't get the one that's crap) what you want is a normal air valve, they come in various configurations, one or more valves so as to run multiple airstones and to balance the airflow to each stone or ornament. You should not however just use the valve to limit airflow, as this damages the pump eventually. You can just let one of two valves bleed off a little air; however make sure another check valve is in the line from the tank to the valves or else you risk water coming out of that valve if it's lower than the tank water level.....You may want a smaller air pump or an adjustable one instead.

Q: I'm installing a shut off valve under my sink. can you tell me all the materials that i need to install it by myself because to hire some body else is very expensive where i live. i need to change the old ones because they are leaking very bad when i want to use the sink.thanks a lot: Get a shut-off valve with the same dimensions as the old one. You'll need the same sizes on both sides of the valve, one the tube end that goes in the wall and the end that goes to the pipe under the sink. If you can, shut the water off to the pipe that goes to that pipe. Take the valve off and bring it with you other wise it's all guess work. Get the compression rings. That's all you have to do is put it on. Don't over tighten the nuts and loosen the compression rings they'll drip. If you do, you can replace them by loosening them with a pliers gently and slipping them of, putting a new ring on. Should be it.

Q: i wanna know the role of TOP ENTRY in this definition it's difference with side entry valve.: Top entry ball valve: One piece body construction, Fire Safe, Full / Reduced Port, Soft or Metal Seated, Antistatic device, Blowout proof stem, Lever operated, Gear Operated or Actuated. Made up of Carbon Steel, Stainless Steel, Low Temp Carbon Steel, Duplex, Super Duplex, Super Austenitic Stainless Steel and exotics like Inconel, Monel, Hastelloy etc.

Q: i have been told that a bad EGR valve (exhaust gas recirculation valve) could cause a car to buck or hesitate in mid range speed at low rpms, thats what my car is doing. i work at autozone and i used our code reader and there was a code that stated EGR flow malfunction anyone else have this problem ever? please help me! i dont wanna spend the $120 if i dont need to!: If an egr valve opens too soon you will have a hesitation problem. Bad egr's do not cause problems with drive-ability at cruising speed. It sounds like your egr is faulty.
